The voluntary immigration of Brazilians in Portugal is a phenomenon that has been evolving since the 1980s and 1990s, constituted by a heterogeneity of projects and motivations. The formation of bicultural Luso-Brazilian couples is part of the migratory project, originating the formation of families crossed by a double cultural reference. The children of Luso-Brazilian couples in Portugal represent a young and understudied population, making it pertinent to understand the generational transmission in this population. To speak of generational transmission is to think of the psychic, conscious and unconscious legacies underlying the temporal experience of family bonds. Therefore, the aim of this research was to study elements of generational transmission in children of Portuguese-Brazilian couples in Portugal. To this end, a qualitative field research was carried out, with the participation of 12 interviewees, seven men and five women, between 18 and 31 years old, children of Luso-Brazilian bicultural couples, whose parents of Brazilian origin voluntarily migrated to Portugal. The results pointed to the constitution of a family system permeated by family stigmas related to gender and nationality. The acceptance of the conjugal couple by the families of Portuguese origin was due to the birth of the participants, showing that the past history of the parental couple and of the families of origin can be integrated by their children. Social stereotypes contributed to the privatization of family relations, in which the transmission of Brazilian culture was restricted to the private sphere. The generational transmission was carried out, above all, by the figure of the woman, through the articulation of practices and values, giving them a place of maintenance of family bonds. We conclude that the family bonds are perceived as transmitters of a cultural heritage, translated into sensorial memories and affective and symbolic value, contributing to the identity autonomy and family belonging, privileging the positive aspects of both cultures.
